SPECIFICATION forming part of Letters Patent No. 392,207, dated November 6,1888. Application filed August 17, 1888. Serial No. 282,979. (No model.)

.To aZZ whom it may concern.-

Be it known that I, SIMON A. KERNS, residing at Rock Island, in the county of Rock Island and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Wheel-Flows, of which the following is a specification, reference being bad to the accompanying drawings, in which- Figurel is a plan, the plow being removed. Fig. 2 is a side elevation. Fig. 3 is a perspective detail showing one end of the axle and a portion of the devices for raising or lowering and leveling the plow. Fig. 4 is a detail, being a section through the parts shown, taken at line 4 of Fig. 2. ,Figs. 3 and 4 are enlarged.

The object of my invention is to provide a wheel-plow with improved devices for raising or lowering and leveling the plow, which I accomplish as illustrated in the drawings and hereinafter described.

That. which I claim as new will be set forth in the claims.

In the drawings, A representsone part of a bent axle.

B is a sleeve upon and secured to the part A of the axle, so that this sleeve B revolves with the axle.

a is an arm extending out from the sleeve B. The outer end of this arm a is enlarged and provided with a rack, b.

c is a slot in the arm a. A

G is the other part of the bent axle, which, as shown, consists of three parts, cl ef, cl being a sleeve located loosely upon the outer end of the sleeve B, 6 being an arm connected with the sleeve (1, and f being a piece of metal bolted, as shown, to the part 6.

g is an arm extending out from the sleeve d, the outer end of which arm is enlarged and is provided with a rack, h.

'i is a slot in the arm 9.

I) is a lever which is located loosely on the sleeve B.

j k are two pins, one on each side of the lever D, which two pins respectively enter the slots 0 and Z is a spring-bolt which engages with the rack h.

m is a thumb-piece or lever pivoted to the E is the plow-beam, which is connected with the axle, as usual.

F is a rack bolted to the plow-beam.

r is another spring-bolt, which engages with the rack F.

s is a thumb-piece or lever pivoted to the lever D.

t is a rod which connects the lever s and bolt 1.

G is a plow.

H H are the wheels.

I is a brace.

u is a boltwhich can be inserted into the sleeve B before it is secured to the axle A.

'0 is a washer.

The sleeve B with its arm a and rack b can be cast together. The sleeve d and the part 6 and the arm 9 with the rack h may also be cast together. The lever D may be made of two parts riveted together. Each of the bolts l 0 1f is supported in bearings, as usual.

In Fig. 2 the dotted lines indicate the wheel H.

The operation is as follows: When the three bolts Z0 1* are all engaged with their racks, the plow will be held in whatever position it may then occupy. If the bolt Z be withdrawn from the rack hand the bolt r be at the same time withdrawn from the rack F, leaving the bolt 0 engaged with the rack d, the operator can then move the lever D either up or down,

which will give to the sleeve B a partial rotation, and as the sleeve 13 is rigidly connected with the part A of the axle, such part A will be at the same time partially rotated, and thus the plow can be either raised or lowered by the change of the position of the part A of the axle. If the bolt 0 be withdrawn from its rack 12 and the bolt r be at the same time withdrawn from its rack F, the bolt Zremaining engaged with the rack h, the operator can then move the lever D either up or down,which will give to the sleeve (1 a partial rotation on the sleeve B, and the plow will be raised or lowered by the changedposition of that part 0 of the axle consisting, as before stated, of the parts d 0]. \Vhen the plow is either raised or lowered, as above described, of course it will be slightly tilted, because the position of only one part of the axle will be changed. The operator can tilt the plow for the purpose of leveling it by releasing either one of the bolts Z or 0 without handling the lever 1). If the bolt 1 only be released from its rack, the part, 0 of the axle will change its position automatically a little and tilt the plow one way. If the bolt 0 only be released from its rack, the other part, A, of the axle will change its position automatically and the plow will be tilted in the opposite direction. The pins j it serve as stops when they come in contact with the ends of the slots, in which they respectively move. Of course the automatic movement just mentioned cannot take place if, when the bolt 1 is withdrawn from its racl ,the stop pin 7; be at the lower end of the slot t; neither can there be an automatic movement when only the bolt 0 is withdrawn from its rack if the pinj be then at the lower end of its slot, both wheels being on the ground. \Vhen the plow has been leveled, the operator can raise or lower it squarely without tilting it by releasing the bolt 0* from its rack F, allowing the other bolts to remain in engagement with their racks and then moving the lever D up or down.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a wheel-plow, a divided and bentaxle, in combination with a sleeve, 3, secured to one part,A,of the axle, a sleeve, d, connected with the other part of the axle and placed loosely upon the sleeve B, a rack, h, connected with the sleeved, a lever, D, loose on the sleeve B, a plow-beam carrying a rack, F, and bolts, as l and r,which can engage with the racks h and F, substantially as and forthe purpose specified.

2. In a wheel-plow, a divided and bent axle, in combination with a sleeve, B, secured to one part,A,of the axle, asleeve, d, connected with the other part of the axle and placed loosely upon the sleeve B, a rack, I), connected with the sleeve B, a lever, D, loose on the sleeve B, a plow-beam carrying a rack, F, bolts, as o and 1', which engage, respectively, with the racks I) and F, substantially as and for the purpose specified.

3. In a wheelplow, a divided and bent axle, in combination with a sleeve, B, secured to one part,A,of the axle, asleeve, (I, connected with the other part of the axle and placed loosely upon the sleeve B. a rack, I), connected with the sleeve B, a rack, it, connected with the sleeve d, a lever, D, loose upon the sleeve B, aplow: beam carrying a rack, F, bolts, as Z, 0, and 1', which can engage, respcctivel y, with the racks h b F,and devices connected with the lever D, for operating the bolts, substantially as and for the purposes specified.
